Definitions

  • the present invention relates to the technology of processing byproduct gas or natural gas and in particular to a process for low-temperature separating gas components.
  • a process of separation is also disclosed in the patent RU 2272973, published on 27.03.2006 , comprising the steps of cooling a gas mixture, expanding the mixture in a spun flow in a nozzle, the mixture being separated into a product enriched with heavy components and a product depleted of said components, channeling at least a part of the enriched product into a fractionating column, channeling at least a part of gaseous products obtained in the fractionating column to the mixture before expanding the last, heating the depleted product at the expense of cooling the gas mixture.
  • US2007/227186A1 discloses a gas separation process with the features of the preamble of claim 1.
  • the technical result targeted by the present invention resides in the improvement of the degree of purifying the outgoing gas.
  • expanding the additionally cooled part of the gas can be carried out in a centrifugal expander or in a throttle valve and/or in a nozzle; some mixture and/or streams obtained from the mixture and having a temperature higher than the dew point of the enriched flow can be added to the enriched flow; likewise the additionally cooled part of the gas can be used in an ejector as ejecting or ejected gas after blending the same with products obtained from the gas mixture.
  • the mixture 1 enters the blender 35 where it is mixed with the gaseous product 17 obtained in the separator 22.
  • the gas 17 is preheated in the compressor 25 and cooled in the air cooling apparatus 27.
  • the mixture 3 is cooled in the heat exchanger 19, the two-phase mixture obtained in the separator 21 is separated into the gaseous product 5 and the liquid product that are expanded in the valves 30, 31 and sent to the column 24.
  • the expanding of the gas 5 can be carried out in a centrifugal expander or in a nozzle. Instead of a multichannel heat exchanger 19, several heat exchangers can be used.
  • the gaseous product 7 is fed from the column to the jet separator 23 where it is expanded in a spun flow in the nozzle and separated into a flow 8 enriched with components heavier than methane and a flow 9 depleted of these components.
  • the enriched flow 8 is fed to the separator 22 where the liquid 14 and the gaseous 17 products are separated, the liquid 14 being fed to the column 24 with the help of a pump 29.
  • the depleted flow 9 is fed into the heating channels of a recuperative heat exchanger 20 and then additionally heated in the heat exchanger 19, compressed in a compressor 26 cooled in an air cooling apparatus 28, a part of gas obtained 10 is used as an outgoing product 11.
  • the other part 12 is additionally cooled in the heat exchanger 20, expanded in a valve 34 and fed to the column 24.
  • the part 6 of the liquid product is used as a cooling agent in the heat exchanger 19.
  • the other part 18 of the liquid product is as well fed, as a cooling agent, to the heat exchanger 19 and is used as an outgoing product.
  • an additional cooling agent 2 can be used in the heat exchanger 19.
  • the gaseous product 17 coming from the separator 22 and being a part of the enriched flow 16 is used in the heat exchanger 19 to cool the gas mixture, compressed in the compressor 25, cooled in the air cooling apparatus 27 and fed to the blender 35.
  • a centrifugal expander and/or a nozzle can be used to expand the additional part of gas.
  • some mixture and/or products obtained from the mixture and having a temperature higher than the dew point of the enriched flow can be added to the enriched flow 8. It will enable to avoid the formation of a solid phase (for example, of dry ice) in the conduits as well as in the separator 22.
  • the additional cooled part of gas after its expansion is fed to the ejector 36 ( Fig. 2 ) where it is used as an ejecting or ejected gas while mixed with the products 7 obtained from the gas mixture, after that the mixture is sent to the nozzle separator 23.
  • the ejector 36 can be used either for lowering pressure in the fractionating column or for lowering energy used for compression.
  • an ejector can be used as well, which will enable a more rational use of energy to compress gas.
  • Table 1 discloses the data for calculating the parameters of flows in the installation shown as an example in Fig. 1 .
  • the Table uses the designations as follows: No is the flow number, T is the flow temperature, P is the flow pressure, the values of the component molar fraction being given in respective lines.
